3D or not 3D: The binocular tolerance to higher order aberrations

For the last decade, thanks to the measurement of higher order wavefront aberrations, we have been able to precise the concept of quality of vision (a new frontier that goes beyond visual acuity). These techniques, first developed for astronomical applications and defense, gave the ophthalmologist new tools, to measure the quality of vision, in healthy subjects and patients. We will go thru the pros and cons of each of the devices, developed for this very purpose and show their current applications. We will finally present new techniques, studying the quality of vision dynamically, in 3D and giving the patient a “preview” of a potential surgical procedure on his quality of vision.
